ULTRASOLVE® INK: Sustainability and high yields in
flexographic printing inks for packaging applications
The ULTRASOLVE® INK is Oxiteno’s line of
process of plastic films, both in flexographic and
as Nitrocellulose-Polyurethane,
oxygenated solvents for printing inks that offers
rotogravure printers. The ULTRASOLVE® INK line
Nitrocellulose-Polyamide, Nitrocellulose-Fumaric,
high performance and sustainability gains. These
also provides the application with high

Life-cycle Assessment (LCA)*
Through the analysis of the impacts established by the Lifecycle Assessment (LCA), it was possible to conclude that the flexographic printing process
performed with the ULTRASOLVE® INK line has less impact on the environment in global terms, such as, on global warming.
